I had a time some years back where I experimented drawing mandalas; well, sort of mandalas. I would meditate for a while and then begin to draw. I’m not an artist at all, and doing these drawings was about freeing something inside me, rather than trying to capture an image or scene. I’d been thinking about trees, obviously, and their place in my life, when I did this mandala.
I used the same design to paint on a medicine shield that now hangs in my study. I know it doesn’t look like any tree on earth, but then it wasn’t intended to!
